BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The present invention relates to a sock related device. More particularly, the present invention relates to a device for facilitating donning a sock on a user's foot.

[0004] 2. Description of the Prior Art

[0005] Numerous innovations for sock donning assist devices have be n provided in the prior art that will be described. Even though these innovations may be suitable for the specific individual purposes to which they address, however, they differ from the present invention.

[0006] A FIRST EXAMPLE, U.S. Pat. No. 2,796,207 to Young teaches a guide device for facilitating the putting on of a stocking, comprising a body member of smooth and flexible material substantially in the shape of the lower leg and foot of a human, said member being open at its lower end and having a slot extending from its open lower end medically along the sole and upwardly to the top of the member, and means for removably connecting a stocking to said member.

[0007] A SECOND EXAMPLE, U.S. Pat. No. 2,828,057 to MacLauchlan teaches a device for putting on a stocking comprising a substantially flat elongated base adapted for placement thereon of a person's foot, a pair of members extending upwardly from the sides of said base and running approximately from the front to the rear of said base, said members each being provided with a hump intermediate the front and rear of said base, a pair of rigid elongated elements respectively connected at one end with said members and extending upwardly and rearwardly of the rear end of said base, the upper ends of said elements being operative as handles for controlling placement of said base, a pair of elongated webs respectively extending from upper portions of said elements approximately to said members, and means for removably attaching the extending ends of said webs to a stocking.

[0008] A THIRD EXAMPLE, U.S. Pat. No. 4,066,194 to Leland teaches a device for assisting one in the donning of a sock, stocking, or like foot covering. In a preferred form, the device comprises a handle member from which laterally and transversely depend a pair of sock expanding and gripping members. The sock expanding and gripping members are designed to be placed within the sock and serve to spread same longitudinally, horizontally and vertically to permit easy entry of the foot. The user then brings the foot covering about the foot and ankle and utilizes a unique combination frame positioner and sock release device to release the sock and withdraw the device.

[0009] A FOURTH EXAMPLE, U.S. Pat. No. 4,284,216 to Leland teaches an improved device for assisting one in the donning of a sock, stocking, or like foot covering. The device comprises a handle member from which laterally and transversely depend a pair of sock expanding and holding members which are adapted to be placed within a sock to spread same for permitting easy entry of the foot of a user. An improved control bar extends between the wire-like handle members and permits the spacing between same to be adjustable to any of a plurality of distances, correspondingly varying the distance between the sock engaging members. An auxiliary holding member may be provided for facilitating use of the device by an amputee.

[0010] A FIFTH EXAMPLE, U.S. Pat. No. 4,756,453 to Pettit et al. teaches a device to assist a person with putting on stockings, or other hosiery, that includes a pair of posts connected by a hinge. Each post is fitted with a hosiery inversion arm. A user places a sock, or the like hose, over both arms, the top inverted and the sock toe extending downward between the arms. The user then spreads the posts apart to stretch the sock open and pushes a foot into the open sock, the sock unfolding as it is mounted on the foot.

[0011] A SIXTH EXAMPLE, U.S. Pat. No. 5,082,154 to French teaches an apparatus for assisting an individual in donning hosiery. The apparatus includes a base member operatively attached to a three legged hosiery support unit having two angles side legs supporting members, and an angled rear support leg member which suspend and expands the opening of an article of hosiery to accept the insertion of the user's foot.

[0012] A SEVENTH EXAMPLE, U.S. Pat. No. 5,632,424 to Maier et al. teaches a sock donning assist device that allows a caretaker to put a sock on a disabled person who can not put the sock on themselves. The sock donning assist device includes a hollow rigid substantially L-shaped frame. The hollow rigid substantially L-shaped frame consists of a plurality of different sized and shaped slender members. The plurality of different sized and shaped slender members form a substantially vertically-oriented portion for retaining a sock during donning wherein the sock has an upper portion and a lower portion, and a horizontally-oriented portion extending forwardly from the substantially vertically-oriented portion of the hollow rigid substantially L-shaped frame for gripping by a user during donning the sock. Prior to donning the sock the substantially vertically-oriented portion of the hollow rigid substantially L-shaped frame receives the lower portion of the sock and the substantially vertically-oriented portion of the hollow rigid substantially L-shaped frame is received by the upper portion of the sock. During donning the substantially vertically-oriented portion of the hollow rigid substantially. L-shaped frame is progressively removed from the upper portion of the sock.

[0013] AN EIGHTH EXAMPLE, U.S. Pat. No. 5,706,988 to Moore teaches a stocking aid device that comprises a pair of rigid handles for ease of manipulation and a U-shaped member which is connected pivotally to the rods about a generally transverse axis with a sufficient degree of freedom to allow the U-shaped member to pivot freely about the axis and slide over the user's heel and up the back of the leg when applying the stocking. The U-shaped member thus follows a curving path under the sole of the foot around the heel and up the back of the leg whilst applying the stocking. This is facilitated by a slight twisting of the rods which provide handles, so as to impede rotation of the U-shaped member. One edge is flared outwardly to form a flange comprising a series of indentations. The indentations are pointed, but are not sharp, such that a sock or stocking is placed into the concave side of the U-shaped member and part of the elasticated rim of the stocking is hooked over the indentations so as to grip the stocking prior to applying a stocking with the device.

[0014] It is apparent that numerous innovations for sock donning assist devices have been provided in the prior art that are adapted to be used. Furthermore, even though these innovations may be suitable for the specific individual purposes to which they address, however, they would not be suitable for the purposes of the present invention as heretofore described.

[0017] BRIEFLY STATED, STILL ANOTHER OBJECT of the present invention is to provide a device for facilitating putting on a sock. A movable frame is received by the sock and is swingingly attached to a stationary frame. The stationary frame rests on the ground and includes a front frame and a rear frame. The movable frame includes a front frame and a rear frame. Each of the front frame and the rear frame of the movable frame has a front portion and a rear portion.
